Based on the data reviewed, concentrations of PCBs detected in sediment along Brandywine Creek may pose a potential health hazard to subsistence fisherman who consume the contaminated fish. Furthermore, PCBs contaminated sediment may serve as a continuing source of contamination for bottom feeding fish.

The available sediment samples represent one point in time,and the direction of change in sediment PCBs concentrationsis not known (i.e., it is not known whether they willincrease or decrease in the future). Therefore, it wouldbe prudent to assess soils on site with regard to theirpotential for future sediment contamination and considerremediation of those soils on the basis of estimated futurerisk.

Assess onsite soils with regard to their potential as a source for future sediment contamination and fish tissue contamination.
